# Key Management

Selen AI utilizes **Hardware Security Modules (HSM)** to perform all signing operations, ensuring the highest level of security for sensitive transaction processes. By keeping private keys within a secure, isolated environment, the system ensures that even if there is a breach, the keys remain protected and inaccessible to malicious actors.

* **Key Isolation and Protection**: Private keys are never exposed outside the HSM, providing a safeguard against any potential system vulnerabilities or compromises.
* **Support for Hardware-Backed Wallets**: Selen AI seamlessly integrates with hardware-backed wallets, offering an additional layer of security for users who prioritize physical security measures for their assets.
* **Multisignature (Multisig) Capabilities**: For institutional use cases, Selen AI supports multisignature wallets, requiring multiple keys for transaction approval, further enhancing security and reducing the risk of unauthorized access.

This HSM-backed signing process ensures that all transaction executions are both secure and resilient, offering peace of mind for users, particularly those in institutional or high-stakes trading environments.
